Very happy with the product. Had terrible posture from 30 years on the phone and computer.
The small fit tight at the beginning, but once I wore it a few times, the fabric stretched abit and now is perfect.
I wear it 2 hours a day and it is like the product instructions said, my back muscles are starting to stay where they should, instead of slouching forward.
At the beginning,
1. I thought it is too small but then it fit very good to my size.
2. I found that it is painful under armpit area, however, when I keep the right posture, there is no pain. It is whole point isn’t it, to remind the right posture.
My posture became better in the days when I use it. I will buy the bigger size for my husband.
Good fit to relieve thoracic back pain from rounded shoulders. I use it when feeling particularly tired or sore to get some relief and to help retrain my posture, but not overuse and get weak
